How can we explain the recent spike in failed login attempts for JumpCloud's Single Sign-On (SSO) service across our SMB client base?

Introduction

The recent spike in failed login attempts for JumpCloud's Single Sign-On (SSO) service across our SMB client base is a critical issue that demands immediate attention. This analysis will systematically identify, validate, and address the root cause while considering both short-term and long-term implications for our product and users.

I'll approach this problem by first clarifying the context, then ruling out external factors before diving deep into the product mechanics, user journey, and potential internal causes. We'll generate data-driven hypotheses, conduct a thorough root cause analysis, and develop a comprehensive plan for validation and resolution.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this might be a recent phenomenon. When exactly did we start noticing this spike in failed login attempts?

Why it matters: Pinpointing the timeframe helps correlate the issue with recent changes or events. Expected answer: Within the last week or two. Impact on approach: A sudden spike suggests a recent change or external event, while a gradual increase might indicate a longer-term trend or systemic issue.

• Considering the scope, I'm wondering if this affects all SMB clients or a specific subset. Can you provide more details on the affected user segments?

Why it matters: Understanding the scope helps narrow down potential causes and tailor our solution. Expected answer: It affects a significant portion of SMB clients, but not all. Impact on approach: If it's widespread, we'd focus on global factors; if limited, we'd investigate segment-specific issues.

• Given the nature of SSO, I'm curious about any recent updates to our authentication protocols. Have we implemented any changes to our SSO service in the past month?

Why it matters: Recent changes could be directly related to the increase in failed attempts. Expected answer: A minor update was pushed two weeks ago. Impact on approach: If there were recent changes, we'd prioritize investigating those; if not, we'd look at other factors.

• Considering potential external factors, I'm wondering about any unusual activity patterns. Have we noticed any signs of increased bot activity or potential security threats?

Why it matters: Distinguishing between user errors and potential security issues is crucial for our response. Expected answer: No significant increase in suspicious activity detected. Impact on approach: If there's unusual activity, we'd involve our security team; if not, we'd focus more on user experience and technical issues.
